Of the possible 2,920 collections during calendar year 1994 (assuming eight 

 collections per day), a total of 2,320 collections were acquired and processed as 

 frequency-direction spectra. A number of collections were lost because of the in- 

 ability to establish or maintain electrically clean phone links to the concentrator on 

 Harvest Platform. An additional number of collections were not processed be- 

 cause data did not satisfy error-checking constraints described in Chapter 3 of this 

 report.
